Sandia National Laboratories is a multi-program laboratory operated by Sandia Corporation for the United States Department of Energy’s National Nuclear Security Administration. Sandia develops and applies science and engineering to enhance national security.

1. Sandia is a multi-program laboratory operated by Sandia Corporation, a Lockheed Martin Company,
for the United States Department of Energy’s National Nuclear Security Administration
under contract DE-AC04-94AL85000.

3. 3
 A system for standardizing and
harmonizing the classification and
labeling of chemicals
 Not a regulation or a standard.
• establishes agreed hazard classification and
communication provisions with explanatory
information on how to apply the system
 GHS Labels and Safety Data Sheets
(SDS)
http://www.osha.gov/dsg/hazcom/ghs.html

4. 4
 Symbols (hazard pictograms)
 Signal words
• "Danger" for the more severe
hazards, and
• "Warning" for the less severe
hazards
 Hazard statement
 Precautionary Statements
and Pictograms
• prevention, response in cases
of accidental spillage or
exposure, storage, and disposal
 Product Identifier (ingredient
disclosure)
 Supplier identification
 Supplemental information

ISO, EU and ANSI requirements
 Most comprehensive source of information
• Hazards, including environmental hazards
• Advice and safety precautions
◦ Transportation, emergency responders, poison centers
 Product related and not specific to workplace
or task
• Written and supplied by manufacturer
 Only for pure substances and some mixtures

16 Sections
Look at Sulfuric Acid SDS provided in Booklet, as we
describe some of the important sections
11

12.  GHS classification of the substance/mixture
and any national or regional information
 GHS label elements, including precautionary
statements.
• Pictograms, black and white reproduction of the
symbols, or the name of the symbol, e.g., flame,
skull and crossbones.
 Other hazards which do not result in
classification (e.g., dust explosion hazard) or
those not covered by the GHS.
12

13.  Description of necessary measures,
subdivided according to the different routes
of exposure, i.e., inhalation, skin and eye
contact, and ingestion.
 Most important symptoms/effects, acute and
delayed.
 Indication of immediate medical attention and
special treatment needed, if necessary.
13

14. Section 6: Handling and Storage
 Precautions for safe handling.
 Conditions for safe storage, including any
incompatibilities.
Section 7: Exposure controls/ personal protection
 Control parameters, e.g., occupational exposure
limit values or biological limit values.
 Appropriate engineering controls.
 Individual protection measures, such as personal
protective equipment (PPE).
14

15.  Reactivity
 Chemical stability
 Possibility of hazardous reactions
 Conditions to avoid (e.g., static discharge,
shock or vibration)
 Incompatible materials
 Hazardous decomposition products
15

16. Section 13: Disposal Considerations
 Description of waste residues and
information on their safe handling and
methods of disposal, including the disposal
of any contaminated packaging.
• May be region, country specific
Section 15: Regulatory Information
 Safety, health and environmental regulations
specific for the product in question.
• May be region, country specific

17. ‣ Drawbacks
• Not always current
• Lack of toxicity information for most chemicals
• Industry focus, not specific to laboratory scale
• Sometimes inconsistent
‣ SDS contains comprehensive information for
chemical management in one place
‣ Keep SDS for each chemical in your inventory
